Name

zmq_term - terminate ØMQ context

Synopsis

int zmq_term (void *context);

Description

The zmq_term() function shall terminate the ØMQ context context.

Context termination is performed in the following steps:

  • Any blocking operations currently in progress on sockets open within context shall return immediately with an error code of ETERM. With the exception of zmq_close(), any further operations on sockets open within context shall fail with an error code of ETERM.
  • After interrupting all blocking calls, zmq_term() shall block until the following conditions are satisfied:
    • All sockets open within context have been closed with zmq_close().
    • For each socket within context, all messages sent by the application with zmq_send() have either been physically transferred to a network peer, or the socket's linger period set with the ZMQ_LINGER socket option has expired.

For further details regarding socket linger behaviour refer to the ZMQ_LINGER option in zmq_setsockopt(3).

This function is deprecated by zmq_ctx_term(3).

Return value

The zmq_term() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.

Errors

EFAULT
The provided context was invalid.
EINTR
Termination was interrupted by a signal. It can be restarted if needed.
